In order to guarantee test product turnover reverberation room, the door opening of certain size must be reserved.When noise fest is carried out, door opening must with soundproof door airtight on, the sound insulation factor of reverberation room soundproof door, intensity must meet corresponding requirements (sound insulation factor at usual gate is greater than 55dB, and can bear the sound pressure of about 160dB).In the past, in order to guaranteed strength and sound insulation factor, way general is both at home and abroad all adopt reinforced concrete structure soundproof door, and thickness is generally greater than 0.5m.The acoustical behavior in sound insulation factor and reverberation room reasonablely can be guaranteed in reinforced concrete structure gate, but because its weight is larger, difficulty of construction is large, and the precision of pouring concrete is comparatively difficult to ensure card, add that the long-time operation opened and closed easily makes ground and bearing guide rail deform, cause gate and doorframe that card easily occurs to wipe, gate will be caused time serious stuck, and maintaining difficulty is larger.
For this reason, provide a kind of easy to use and can ensure that the sound insulation gate structure of acoustical behavior in sound insulation factor and reverberation room is very necessary.
Summary of the invention
In order to solve the problem, the present invention proposes sound insulation gate, a kind of acoustic reverberation room, it is possessing the inner acoustic energy of reflection reverberation room and under ensureing the prerequisite of the function of external noise environment, because Steel Structure Gate adopts mechanical processing tools, dimensional accuracy is ensured, ensure that the operational reliability at gate.
To achieve these goals, present invention employs following technical scheme:
Sound insulation gate, acoustic reverberation room of the present invention, comprise the inner gate skeleton welded with i iron by channel-section steel and the gate inner surface steel plate be arranged on skeleton two sides, gate and gate outer surface plate, inner surface steel plate thickness is more than 30mm, outer surface plate thickness is more than 20mm, the gross thickness of gate skeleton and surfaces externally and internally steel plate is 500mm, on the region of gate surfaces externally and internally surrounding width 300mm, the projection of projecting thickness 20mm is to carry out fitted seal with pressure bladder, wherein, sound absorption damping material is filled with in the gap of gate skeleton.
Further, gate inner surface steel plate and gate outer surface plate are set on skeleton by the mode of mechanical fixing mode or welding.
Further, the side at gate is also provided with side steel plate.
Further, pressure bladder is arranged in sealing device, and sealing device is arranged on door leaf and body of wall overlaps on the body of wall of part.
Further, projection after pressure bladder inflation and its carry out being sealed and matched and to be tightly connected to be formed between gate and body of wall.
Reverberation room soundproof door of the present invention adopts steel structural form, gate surfaces externally and internally adopts steel plate form, the inner steel frame construction that adopts adds sound absorption material, enable gate on the basis ensureing sound insulation factor and reverberation room acoustic efficiency, greatly alleviate the overall weight at gate, simultaneously because Steel Structure Gate adopts mechanical processing tools, its dimensional accuracy can be guaranteed, and ensure that the operational reliability at gate.
